How much is that actress in the glass booth?

Tilda Swinton turns sleeping into an art form

Turn about is fair play. After having put audiences to sleep with three Chronicle of Narnia films, Tilda Swinton returned the favor by taking a 6 hour catnap for all to see last weekend at New York's Museum of Modern Art.

The British actress made her surprise cameo as an objet d'art on Saturday. The glass booth was part of an installation called The Maybe.

Time Magazine reports, "Swinton first performed this role in 1995 at London’s Serpentine Gallery — attracting more than 22,000 visitors — and again in 1996 at Rome’s Museo Barracco. The exhibit is being put on in collaboration with Turner Prize–shortlisted artist Cornelia Parker."

Swinton will be making 6 more unbilled appearances throughout the year. Needless to say, she was not the first performer to use a glass booth as a prop.
